SPECIFICATION forming part of Letters'Patent No. 382,636, dated May8,1888.

Application filed January 21, 1888.

To all whom it may congerm Be it known that I, STEPHEN BURDSALL, acitizen of the United- States, residing at Fremont, in the county ofSandusky and State of Ohio, have invented certain new and usefulImprovements in Running Gears for Vehicles; and I do declarethefollowing to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itence being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, which form a part of thisspecification.

This invention relates to certain improved features in running gears forvehicles, in which the perch-heads are made so as to be attached to andremoved from the upper and lower section of the fifth-wheel plates, asshown in Letters Patent issued to me on May 3,1887, No. 362,423, thepresent device being an improvement on said Letters Patent. Thecouplings of the king-bolt in the former patent are located over andunder the-axle. In the present device I have what is known as a rearcoupling, it being much preferred and much cheaper in construction, moreconvenient to range in turning as the axle oscillates on its bearings,as will be hereinafter more fully set forth, and the essential featurespointed out particularly in the claims.

In the accompanying drawings, forming a part of the specification,Figure 1 is a viewin perspective of my improved running gear mounted onthe iron axle, the wood part and head-block being removed. Fig. 2 isacross; section taken on the dotted line :0 0c of Fig. 1, showing alsothe wood-work in cross-section. Fig. 3 is a perspective of theupperperch-head iron. Fig. 4 is a perspective of the binding platelocated against the under face of the iron axle in Fig. 1.

A represents the iron axle; A. the wood part; B,theupper andOthe lowerfifth-wheel plates. Z Z are the rub-irons of the lower, and Z therub-irons of the upper, plates of the fifth- F is the head-block.

. His the upper perch-head, having the two perch-prongs c c.

D is a rear extension or ledge formed integral with the perch-head andhaving a hole, e. R is a longitudinal channel formed in the up per faceof the perch-head, which is'made to receive the body of the uppersection, B, of the.

fifth-wheel, as shown in Figs. 1 and 2.

The section B of' the fifth-wheel has formed integral therewith theforwardly projecting nose J, having a-hole, a, which'receivcs thevertical stem N I of the perch-head H, thereby formingapivotal bearinginfront of the axle. The plate 0 of the fifth-wheel has a rearwardly andupwardly projecting prong or arin,

E. (See Fig. 2.) Said arm has a lug or bolt,

S,madefastthereto. Saidbolt passes through the hole e of the perch-headH, being secured thereto by means of the nut m, thus forminga rearpivotal bearing.

The plate Pis provided with end extensions, '70 4 15, having holes 0' toreceive the yoke Y,by which said plate is secured to the under face ofthe axle A, as shown in Fig. 2. Projecting from the rear edge of theplate Pis an arm, t,

having an annularshoulder, 7 and depending 7 lug or bolt S.

H represents the under perch-head, which has rear extensions, t, for atwo-part perch or reach. Its forwardly-extending stem or arm W isprovided with a hub, G, having a hole through it to receive the bolt S,and an annularchamber, O, in its upper face, to receive the annularshoulder h of the arm 15 of the plate P, being secured thereto by meansof the hut a, (see Figs. -1 and 2,) whereby a second rear pivotalbearing for-the axle is formed, and on said pivotal bearings the foreaxle oscillates as the vehicle is turned. I

N is a vertical extension-0f the arm W, its

upper end being secured to the nose orprojecv tion J of the upperfifth-wheel plate, B, by means of the nuts V V, thereby forminga supportforward of the axle.

The springs D',the head-block F, and plate B of the fifth-wheel aresecured to the perch-head 95.

H by means of theyokes f passing through the perch-head, and having nuts0' on their lower ends, as clearly shown in Fig. 2.

I have shown in the accompanying drawings the perch-heads having eachtwo rearwardlyprojecting prongs. Such is the style for what is known asa doubleperch vehicle; but to use the plates B C on a vehicle having asingle perch I attach perch-heads constructed identical with the onesshown, excepting that they have but one rearwardly projecting prong,which receives the single perch or reach.

It will be observed that the pivot-bearingsin the rear of the axle areshort and strong, and as the bolts S S are made fast to or formedintegral with the supporting-arms there are no bolts to work loose, dropout, or to rattle, thus making a durable and cheap coupling, allowing agreater swing of the fore axle, whereby the vehicle can be turned aboutin less space than as heretofore constructed.

I amawarethatheretoiore therunning-gears of vehicles have beenconstructed with pivotal hearings in the rear of the axle; but I am notaware that perch-heads made so as to be attached to or be detached fromthe fifth-wheel plates have been provided with such roar pivotalbearings.

Having thus fully set forth my invention,

perch-prongs, and rear extension, D,with hole 6, the fifthwheel plate G,having the rearwardly'extending arm E, said arm being pivoted to theextension D of the perchhead, the perch-head H, having one or morerearwardlyextending perch-prongsand forwardextension, VV,the hub G,formed therein and having ahole through said hub, the plate 1?, locatedunder the fore axle'and having the rear extension, t, with dependingbolt S, said bolt being pivotally connected to the hub G and having thenut n, as and for the purposes specified.

2. In combination with the fifth-wheel plateB, the detachable perch-headH, having the rearwardly-extending ledge D, and the fifth-wheel plate 0,having the rearwardly-extending arm E, said arm having a pivotalconnection with the ledge D of the perch-head, and the plate I, havingthe rear extension, t, with depending prong S, the perch-head H, havingthe forward extension pivotally connected to the prong t of the plate I?in the rear of the axle, and its vertical prong N, pivoted to the nose Jof the fifthwheel plate B in advance of said axle, substantially as andfor the purposes specified.

In testimony whereof I affix my signature in presence of two witnesses.
